IMPROVEMENT IN vTURN-BUCKLES.

Specification forming pari of Letters Patent No. 136,910, dated March 18, 1873.

To all whom it may concern:

Be it known that 1 TAcITUs GAILLARD, ot' Brooklyn, E. D., in the county of Kings and State of New York, have invented an Improvement in 'lightening-Screws for Braces, Tie-Rods, Src.; and the following is declared to be a correct description thereof:

TighteningLscrews, sometimes called turnbuckles, have been made with two rods eX- tending from a nut to an eye, through which the bolt passes, and the head is between these rods, and the screw portion of the rod also is between the saidlside rods. In this case, the screw is exposed to atmospheric action,and becomes rusty. In other instances a pipe has extended from the nut to the eye so as to inclose the head of the rod, and also the nut,` and this pipe had to be turned in tightening or loosening the screw-rod.

My invention consists in a tubular socket, Welded upon the end of one rod, and receiving loosely the endmof the other vrod where the screw-thread is cut, in combination with a nut The tube a is made with a anged end, b, and around this is a ring, c, that is sufficiently loose to turn freely upon such tube a, and d is the nut made with a cylindrical extension, e, that'surrounds the iiange b and ring c, and the end of this cylinder e is closed or bent over around the ring c, so as tosecure the same firmly. The screw-thread in the nut d is adapted to flt the screw upon the rod f, and

the tube a is of a size to freely receive said screw-rod f.

It is now to be understood that this tightening device can be made with accuracy and rapidity, and be adapted for attachment to the rod or brace g; hence there is great convenience in this tightener, because after the lengths of the rods or braces have been determined the pipe a can be welded upon the rod that does not have the screw-thread, and the parts are ready for use; and it is only necessary to tighten or slacken the parts that the nut d should be revolved byasuitable wrench.

I claim as my inventionrlhe nut d, made with a cylindrical extension, and the ring c, in combination with the tube a, flange b, screw f, and rod g, substantially as set forth.

Signed by me this 28th day of March, A. D. 1872.
